For wireline service providers, high bandwidth delivery like fiber to the home (FTTH), digital subscriber line (DSL), and fixed wireless require broadband equipment located far from the central office, often in outdoor environments.

Broadband equipment can be powered locally, with utility AC connecting to a power conversion device dedicated to the equipment, or remotely, with power delivered from a centralized site using copper cable pairs. The right solution depends on location, access to utility power, and the power consumption of the broadband equipment.

EnerSys® local power solutions include wide varieties of rectifiers, ruggedized UPS systems, a full suite of batteries and outdoor cabinets that can be tailored to each application. For remote line power (RLP), we have the broadest range of upconverters and downconverters to power DC or AC loads.


Our wide range of outside plant cabinets and rugged power systems can be tailored to any FTTH, DSL or fixe wireless application. Cabinets include power systems of various sizes plus space for broadband equipment and batteries. Our extensive line of shelf-mounted power systems come with various distribution options and a built-in system controller. EnerSys batteries include traditional Valve Regulated Lead Acid (VRLA) as well as Thin Plate Pure Lead (TPPL) varities.

As the global leader in deployment of RLP systems, we offer a wide range of solutions. Up converter options include modular, indoor units as well as sealed devices installation outdoors. At the far end, our various downconverter options include IP68 sealed modules.




As the world leader in stored energy solutions, EnerSys provides integrated systems and services for many types of markets and industries.

The Power of Loop Reduction

Deploying the DSLAM deep into the network reduces the amount of copper between the DSLAM and the end users. Programs like these that shorten, or reduce, the copper loop in order to boost bandwidth delivery have come to be called Loop Reduction programs.
